@akinLiu It shouldn't be throwing this warning. Are you sure your copy of JSONKit is updated?

[akinLiu]

@dhilipsiva I use pod, this is my pod config: pod 'JSONKit', '1.5pre',there is still worning!

@akinLiu Looks like 1.5pre ( https://github.com/CocoaPods/Specs/blob/master/JSONKit/1.5pre/JSONKit.podspec#L8 ) is pointing to the commit 0aff3de which clearly doesn't include ( 0aff3de...master#L0L2791 ) this fix. So try pulling the latest code from GitHub manually or update the Specs repo of Cocoapods to point to the latest.
